Привет.
Постоянно теряется связь VPS с остальной сетью. На некоторое время
лечится ребутом VPS, потом опять пинга нет.
Подозреваю что проблема с арпами, но точно определить не могу.
Может есть у кого какие-то идеи?
Конфигурация такая:
Сервер, на котором крутится телефония+кучка остальный сервисов.
Телефония настроена в VPS.
На сервере 2 физических интерфейса: eth0 основной, и eth1 используется
для связи телефонии с провайдером и прокинут в VPS через --netdev_add
VPS для связи с остальной сетью использует venet.
Вот настройки на хардноде:
